Summary Introduction

To determine:

The definition of gamete.

Introduction:

A gamete is the cell containing the genetic information that is forms in human reproductive organ which fuses with other sex gamete at the time of fertilization.

Explanation of Solution

The reproductive system ensures the survival of human species by producing and nourishing gametes in the reproductive organ (gonad).

In humans there are two types of gametes:

  • Ova/egg: It is produced by female gonad (ovaries) present in adult females, containing single set of chromosome. Every month one immature gamete called as oocyte is produced by single ovary under the influence of hormones and later turns into ova at the time of fertilization.
  • Sperm: It is the male gamete produced by male gonad (testis) present in adult males with single set of chromosome. About half a billion sperms are produced every day by adult male and during the ejaculation sperms are mixed with the secretion of accessory glands and forms semen which is discharged from male reproductive organ.

Molecular Biology Please help with question. thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold 6. Mutations in the promoter that prevent binding of RNA polymerase 7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase
Molecular Biology Please help and there is an attached image. Thank you. A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter. A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.
Molecular Biology Please help. Thank you. Discuss/define the following:(a) poly A polymerase (b) trans-splicing (c) operon
